MARTIN A". COOK AND JOSEPH HAFNER, OF'NEW YORK, N. Y. I ALARM-SIGNAL FOR AUTOMOBILES.

To all whom it may concern:

Be it known that we, MARTIN A. 000K and JOSEPH HAFNER, citizens of the United States,

residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Alarm-Signals for Automobiles, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This inventionrelates to signal or alarm devices for automobiles; and the object thereof is to rovide improved means for operatin an or inary horn or similar alarmdevice; an with this and other objects in view the invention consists in a fied constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying' drawings form a part, in which the separate parts of our improvement are designated by suitable reference characters in eachof the views, and in which r Fi ure 1 is a side view of an automobile provided with our improved signal or alarm operating device, part ofthe construction being in section Fig. 2 a central vertical section through the operating device; Fig. 3, a artial section on the line 3 3 of Fig. 2, and ig. 4 a section on the line 4 4 of Fig. 2.

In'the drawings forming part of this speciiication, reference bein made to Fig. 1, we have shown anautomdbilefpart of one side of which is broken'away so as to show the in the practice of our invention we mount in the floor a, vertically b, a vertically-arranged tubular casing 0, having a detachable cap 0 and passed vertically throu h the casing 0 is a rod 03, provided within said casing, with a collar or similar device d and a spiral spring (i which bears on the bottom of said casing and normally serves to force the rod (1 upalso provided at its upper end with a pressure-head. d, to which in practice one foot of the operator of the vehicle is applied in order to sound the alarm or signal device, and the lower end of the rod d is also provided with a detachable pressurehead (1 i Secured to the floor a is a yoke-shaped or similar frame or hanger e, in the bottom of which is secured a vertically-arranged tubular cash-1g f, and said casingf is provided in the top portion. thereof with a spider frame or Specification of Letters Patent.

support f in which is a verticallyearran ed central tube f through which is passed a vertically-movable rod 9, provided, at its upper end with a pressure-head g and mounted on the rod g, between the tube f 3 and the l pressure-head g is a s ressible air-bul h,

We also provide a com er, rubber andcanwhich is composed of rub cured to the upper end of the tubular easing also provided in the top portion thereof with an air-inlet port or passage k controlled by a valve it, which opens inwardl 1 Connected with the lower end of the tubular casing f is a flexible pipe or hose 'i, which is carried upwardly and forwardly, as shown in Fi 1, and connected with the usual horn or 0t er signal or alarm device 1', and the operation will be readily understood from the foregoin description when. taken in connection with the accompan ing drawings and the following statement t ereof.

Whenever it is desired to sound or operate the. horn or signal device 9', the o ierator of the vehicle presses his foot on the lead 62* of the rod d. This operation forces the rod (1 downwardly, and the rod (1 compresses the bulb h or forces the top portion thereof downsaid bulb through the pipe or hose i, and the horn or si nal device 13 operated, as will be readily understood.

\Vhenthe pressure is removed from the rod d, said rod is forced upwardly into its nor mal position b the spring di and the bulb h is also force into its normal osition, as. shown in full lines in Fig. 2, by t e spring g and rod g, and at this said bulb through the port or passage h, and when said bulb is compressed or forced downwardly, as hereinbefore described, the valve h closes the port or passage b and the air in the bulb can only escape or hose 1').

\ Although we tion on the line 3 3 of Fig. served that said Fig. 3 is a plan view of the have described Fig. 3 as a seciral spring 9, which 1 normally serves to hol the rod-g in its highest position, as shown in-full lines in Fi 2.

f, and the central top portion of saidbulbis.

sure-head d of the rod cl, and thebulb h is.

vas, or any other suitable material, andsaid I bulb is provided with a neck ht, which is se;

wardly, and this operation. forces the air in time air rushes into a through the pipe 2, it will be ob particular means for securing the the tubular struction l ,movab casin c, which is secured in the floor a, of the vehic e with the cap 0 removed, the rod d be ing shown in section, and said casing c is preferably provided midway thereof with a flange or rimc by which it is secured to the floor a. Our invention, however, is not limited to any casing c in the floor a, nor to any particular form or construction of the hanger or frame 1% by which casingf and the bulb h are separated, and various changes in and modifications of these and other parts of the conrein shownand described may be made Without departing from the spirit of our invention or sacrificing its advantages.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

The herein-described means for operating the signal device of an automobile or other vehicle, comprising a hanger secured to the bottom of the floor of the vehicle, a tubular casing secured in the floor of the vehicle and passin Vertically therethrough, a vertically- %e rod mounted in said casing and extending above and below the floor of the vehicle, a spring within said casing for normally holding said rod in a raised position, a tube secured in the bottom of the hanger in line with said rod, a compressible bulb placed within said hanger and connected with said tube in line therewith and with said rod, a spring-supported vertically-nmvab1e rod mounted concentrically in said tube and ex tending upwardly in said bulb in line with said rod and adapted to hold said bulb in an expanded position, and means for admitting air to said bulb when expanded, said bulb being adapted to be compressed by the depression of said rod.

in testimony that we claim the foregoing as our invention we have signed our names, in presence of the subscribing witnesses, this 2d day of September, 1905.
